Warning (Continued)
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park (Automatic
Tr a n s m i s s i o n )0187.
Make sure the shift lever is fully inP(Park) before starting the engine.The vehicle has a shift lock control.Yo u m u s t f u l l y a p p l y t h e b r a k e p e d a lthen press the shift lever buttonbefore you can shift from P (Park)while the ignition key is in ON/RUN.If you cannot shift out of P (Park),ease pressure on the shift lever andpush the shift lever all the way intoP(Park) as you maintain brakeapplication. Then move the shiftlever into another gear. SeeShiftingout of Park (AutomaticTr a n s m i s s i o n )0188.
R:Use this gear to back up.
Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Shift to
R(Reverse) only after the vehicle
is stopped.
To r o c k t h e v e h i c l e b a c k a n d f o r t h t oget out of snow, ice, or sand withoutdamaging the transmission, seeIfthe Vehicle Is Stuck0178.

196 Driving and Operating
Using ABS
Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You may hear the ABSpump or motor operating and feelthe brake pedal pulsate. This isnormal.
Braking in Emergencies
ABS allows you to steer and brakeat the same time. In manyemergencies, steering can helpmore than even the very bestbraking.
Parking Brake
To s e t t h e p a r k i n g b r a k e , h o l d t h ebrake pedal down and pull up on theparking brake lever. If the ignition ison, the brake system warning lightwill come on. SeeBrake SystemWarning Light011 4.
To r e l e a s e t h e p a r k i n g b r a k e , h o l dthe brake pedal down. Pull theparking brake lever up until you canpress the release button. Hold therelease button in as you move thebrake lever all the way down.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Brake Assist
The Brake Assist feature isdesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplement thepower brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this time isnormal and the driver shouldcontinue to apply the brake pedal asthe driving situation dictates. TheBrake Assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.

The speedometer reading can bedisplayed in either English or metricunits. SeeDriver Information Center(DIC)0121.Theincrementvalueused depends on the unitsdisplayed.
Passing Another Vehicle WhileUsing Cruise Control
Use the accelerator pedal toincrease the vehicle speed. Whenyou take your foot off the pedal, thevehicle slows down to the previousset cruise control speed. Whilepressing the accelerator pedal orshortly following the release tooverride cruise control, brieflymoving the thumbwheel towardSET/- will result in cruise control setto the current vehicle speed.
Using Cruise Control on Hills
How well cruise control works onhills depends on the vehicle speed,load, and the steepness of the hills.When going up steep hills, youmight have to step on theaccelerator pedal to maintain thevehicle speed. When goingdownhill, you might have to brake orshift to a lower gear to keep your
speed down. If the brake pedal isapplied, cruise control willdisengage.
Ending Cruise Control
There are four ways to end cruisecontrol:
.To d i s e n g a g e c r u i s e c o n t r o l ,step lightly on the brake pedal orclutch for manual transmission.
.Press*.
.Shift the transmission toN(Neutral).
.To t u r n o f f c r u i s e c o n t r o l ,
press5.
Erasing Speed Memory
The cruise control set speed is
erased from memory if5is pressed
or if the ignition is turned off.

of reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.
SeeTire Pressure MonitorOperation0258.
SeeRadio FrequencyStatement0317.
Tire Pressure Monitor
Operation
This vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, excluding the spare tireand wheel assembly. The TPMSsensors monitor the air pressure in
the tires and transmit the tirepressure readings to a receiverlocated in the vehicle.
When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning lightlocated on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the Tire and LoadingInformation label. SeeVehicle LoadLimits0178.
The low tire pressure warning lightcomes on at each ignition cycle untilthe tires are inflated to the correctinflation pressure.
The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. This
could be an early indicator that theair pressure is getting low and mustbe inflated to the proper pressure.
ATire and Loading Information labelshows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. SeeVehicle LoadLimits0178,foranexampleoftheTire and Loading Information labeland its location. Also seeTirePressure0256.
The TPMS can warn about a lowtire pressure condition but it doesnot replace normal tiremaintenance. SeeTire Inspection0260,Tire Rotation0261andTires0248.
Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only

the GM approved tire sealant
available through your dealer or
included in the vehicle.
TPMS Malfunction Light
The TPMS will not function properlyif one or more of the TPMS sensorsare missing or inoperable. When thesystem detects a malfunction, thelow tire warning light flashes forabout one minute and then stays onfor the remainder of the ignitioncycle. The malfunction light comeson at each ignition cycle until theproblem is corrected. Some of theconditions that can cause this tocome on are:
.One of the road tires has beenreplaced with the spare tire. Thespare tire does not have aTPMS sensor. The malfunctionlight should go off after the roadtire is replaced and the sensormatching process is performed
successfully. See "TPMS SensorMatching Process" later in thissection.
.The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. Themalfunction light should go offafter successfully completing thesensor matching process. See"TPMS Sensor MatchingProcess" later in this section.
.One or more TPMS sensors aremissing or damaged. Themalfunction light should go offwhen the TPMS sensors areinstalled and the sensormatching process is performedsuccessfully. See your dealer forservice.
.Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommendedcould prevent the TPMS fromfunctioning properly. SeeBuyingNew Tires0263.
.Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.
If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight comes on and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thetires or replacing one or more of theTPMS sensors. The TPMS sensormatching process should also beperformed after replacing a sparetire with a road tire containing theTPMS sensor. The malfunction lightshould go off at the next ignitioncycle. The sensors are matched tothe tire/wheel positions, using aTPMS relearn tool, in the followingorder: driver side front tire,passenger side front tire, passengerside rear tire, and driver side rear.
